Resinous penetration permeable pavement material and manufacturing method thereof

Abstract

The present invention discloses a resin infusion type water-permeable pavement material, comprising: a basic bituminous mixture, waterborne epoxy resin, a waterborne curing agent, a toughening agent and a diluting agent; and the basic bituminous mixture comprises coarse aggregate, fine aggregate, fillers and high-viscosity modified bitumen. A water-permeable pavement prepared by the material provided by the present invention has excellent interface bonding capability, favorable road utilization performance and functional performance.

We claim: 
     
       1. A preparation method for a resin infusion type water-permeable pavement material, characterized in that said method comprises:
 selecting a plurality of filler particles and a high-viscosity bitumen; 
 putting basalt, diabase or diorite into a stirring device and stirring for 60 s; adding the high-viscosity bitumen and stirring for 90 s; then, adding the plurality of filler particles and stirring for 90 s; and heating the stirring device to a temperature of 170° C. to obtain the basic bituminous mixture; 
 adding a waterborne epoxy resin in a container, and adding a waterborne curing agent, a toughening agent and the diluting agent in the waterborne epoxy resin and stirring evenly to form a resin mixture; and 
 infusing said basic bituminous mixture into the resin mixture and maintaining for 1 to 2 h to obtain the resin infusion type water-permeable pavement material; 
 absolute viscosity of said high-viscosity bitumen is 87000 Pa·s at 60° C., and softening point is 95° C. 
 
     
     
       2. The preparation method for the resin infusion type water-permeable pavement material of  claim 1 , characterized in that before said basalt, diabase or diorite, said plurality of filler particles and said high-viscosity bitumen are mixed, said basalt, diabase or diorite and said plurality of filler particles are respectively heated to 165° C. and the heating temperature of the high-viscosity bitumen is 170° C. 
     
     
       3. The preparation method for the resin infusion type water-permeable pavement material of  claim 1 , characterized in that the mass ratio of said basic bituminous mixture to said resin mixture is 100:20-25. 
     
     
       4. The preparation method for the resin infusion type water-permeable pavement material of  claim 1 , characterized in that the void of said basic bituminous mixture is 30% to 35%. 
     
     
       5. The preparation method for the resin infusion type water-permeable pavement material of  claim 1 , wherein
 said plurality of filler particles are limestone mineral powder; 
 said toughening agent is dioctyl phthalate or dibutyl phthalate; and 
 said diluting agent is xylene.
